this is the error that i am getting . .don't know what to do

Here EmpMgmtPU is the name of the database

--

Caused by: javax.resource.ResourceException: Wrong driver class [class com.mysql.jdbc.Driver] for this connection URL [jdbcmysql://localhost:2345/EmpMgmtPU]

[lafr]

Seems you're missing a colon in your database URL: jdbc:mysql://localhost:2345/EmpMgmtPU

[nikhil_yadav3]

Hey

<connection-url>jdbcmysql://localhost:2345/EmpMgntPU</connection-url>

[lafr]

Yes, as I wrote before. Change jdbcmysql to jdbc:mysql.

[nikhil_yadav3]
